After a recent power outage, my Magnavox ZV457MG9 VCR/DVD recorder combo will not power up. The power light, clock display and the VHS/DVD source select lights all flash on and off. I have removed the power over night with no success. I have tried holding the standby/power button down for 20 seconds or more, with no effect. Does anyone have suggestions, or is it trash? Although I don't use it daily, it is used several times a week.
